Hella Supertone Horns, installed. *pics*

[Bwana]

Just test fit my new horns. Sorry stock grillers...this wont work for you. I used the bolts for the hood latch. Fits perfectly.

Doing the wiring some time this weekend.

That's gonna be loud as Hella!

Looks great Scott! After trying the Hellas on my Legacy with and without the relay, (used stock twin horn wiring), I'd encourage you to go to the extra work using the relay and 14-16ga wiring. Volume was incrementally louder. You'll love it the first time you chase someone back where they belong with those "fire-breathers"!

How does the relay hook up? The instructions that came with them basically say: Plug in the positive, plug in the negative. That's all.

Do I take the power off the stock wires, and just extend the wires to reach the horns?

I like it.

I'm also intrigued by the grille. Did you notice any gain/loss in cooling by dumping the stock piece? How do you have the mesh attached? Is that stainless, Alum, or ??

Like I said in your PM, check the amps on the horns and your Horn fuse (either under the hood or the kick panel).

If the new horns draws lower amp, you are set. Connect the + to + and - to - side of the horn. I don't think they are labled. So It should not matter. However, if the new horns' amp draw is larger, you are going to trip the breaker and blow the fuse.

Use a relay. Relay is nothing more than a switch. It'll have 2 + and 2 - terminals. Power and switch. Power goes to the current horns and switch to the new horns (or is that the other way round). I can tell you if I see it in person.

The wiring diagram I have shows the OEM horns driven by a relay. Seems you could simply extend the original wiring up to the new horns. Am I missing something here?

[RojoRocket]

Scott, You'll need to use the existing horn lead as the "actuator" and tie it to terminal 86 on the relay. Pin 30 of the relay goes to (+) terminal on the battery (fused of course!). The horns should be well grounded (to their mounting points) and the horn "hots" go to pin 87, and 85 goes to Ground as well.

lee and Lwin, the light gauge wire is the downfall of the OE wiring, so it's best to pull fresh battery source straight from the Battery. Or, maybe yours truly is just being anal about the whole thing!

Edited for clarity, and safety! Thanks Lwin!

Now I can't recall, and didn't mark my diagram, which Subaru does, push (+) or (-) to the horns, but the horns should be well grounded(to their mounting points) and the "hot" goes to pin 87 and 85 goes to Ground as well.

I agree with you there about OE wire being too thin. When I did mine, I just hooked them directly to the OE wires without any trouble.

But If you can I always recommand a relay and a fuse. Safer that way.

here is the link to the Hella Supertone horn specs: http://www.rallylights.com/hella/supertone_horn.asp

Click HERE to see the wiring diagram using a relay.

Stock horns typically have an output of 97dB. The decibel scale is logarithmic and therefore the sound pressure doubles for every increase of 3 points, i.e. a horn with 118dB is approximately seven times as loud as a stock horn.

I did the wiring today. I didnt use the relay. I cut off the connectors of the stock horns, and extended them with 12ga wire long enough to reach the horns. I use 12ga wire to ground them.

They sound very similar to stock horns, except 10 times louder. They are awesome. And I got to use them right after I finished! There's a stop sign right by my house that people rarely stop at. Of course, when I pull up to the sign, some idiot on his cell phone blows right through the sign. I lay on the horn, and he dropped his phone because he was so startled!!

Soo awesome...I recommend everyone upgrade their horns.

How do they sound compare to mine? I am trying to get a hold of electronic horn. Once I get them, the current ones on mine goes to the galant.

They sound more...high pitched. They sound like they fit the car. Yours sounded like they would come from an F-150 or something.

Cool. I'd have to hear them.
